ATI Capstone Comprehensive Assessment B
1. A nurse is teaching a patient with hypertension about the DASH diet. What is the most important instruction to include?
- A. Increase the patient's intake of fruits and vegetables.
- B. Limit the patient's intake of saturated fats.
- C. Encourage the patient to reduce sodium intake.
- D. Recommend the patient avoid caffeine.
Correct answer: C
Rationale: The correct answer is to encourage the patient to reduce sodium intake. The Dietary Approaches to Stop Hypertension (DASH) diet emphasizes reducing sodium intake to help manage hypertension. While increasing fruits and vegetables (Choice A) is important in the DASH diet, reducing sodium intake is considered more crucial. Limiting saturated fats (Choice B) is beneficial but not as critical as reducing sodium. Avoiding caffeine (Choice D) is not a specific recommendation of the DASH diet for managing hypertension.
2. A nurse is caring for a patient with heart failure who has developed pulmonary edema. What is the nurse's priority action?
- A. Administer a diuretic as prescribed.
- B. Place the patient in a high Fowler's position.
- C. Administer oxygen via nasal cannula.
- D. Monitor the patient's lung sounds every 2 hours.
Correct answer: B
Rationale: The correct answer is to place the patient in a high Fowler's position. This position helps improve lung expansion and oxygenation in cases of pulmonary edema by reducing venous return to the heart and enhancing respiratory mechanics. Administering a diuretic (Choice A) can be important but is not the priority over positioning in this situation. Administering oxygen (Choice C) is essential, but the priority action for improving oxygenation is the positioning of the patient. Monitoring lung sounds (Choice D) is crucial for ongoing assessment but is not the priority action when the patient is in distress with pulmonary edema.
3. A patient is being treated for dehydration. Which lab result would support the diagnosis?
- A. Elevated hemoglobin
- B. Low sodium level
- C. High white blood cell count
- D. Elevated BUN
Correct answer: D
Rationale: Elevated BUN levels are a characteristic finding in dehydration due to reduced kidney perfusion and increased reabsorption of urea. Hemoglobin levels might be elevated in conditions like polycythemia vera, not directly related to dehydration. A low sodium level could be seen in conditions like hyponatremia. A high white blood cell count is more indicative of infection or inflammation rather than dehydration.
4. How can a healthcare provider prevent pressure ulcers in an immobile patient?
- A. Turn the patient every 4 hours.
- B. Provide the patient with a special mattress.
- C. Elevate the patient's legs to reduce pressure.
- D. Limit the patient's movement to reduce friction.
Correct answer: B
Rationale: Providing the immobile patient with a special mattress is an effective way to prevent pressure ulcers. Special mattresses help distribute pressure evenly and reduce the risk of developing pressure ulcers by relieving pressure on sensitive areas. Turning the patient every 4 hours (Choice A) is a standard practice to prevent pressure ulcers but may not be as effective as using a special mattress. Elevating the patient's legs (Choice C) can help with circulation but may not directly prevent pressure ulcers. Limiting the patient's movement (Choice D) can lead to other complications and is not a recommended method for preventing pressure ulcers.
5. A client with HIV-1 starting therapy with ritonavir and zidovudine asks why both medications are necessary. What explanation should the nurse provide?
- A. Taking two medications ensures a faster recovery.
- B. The medications work best together to improve your immune system.
- C. Taking the 2 medications together keeps you from becoming resistant to either of them.
- D. These medications target different parts of the virus.
Correct answer: C
Rationale: The correct answer is C because taking two medications together helps prevent the development of drug resistance in HIV treatment. Choice A is incorrect because the primary goal of combination therapy is not necessarily a faster recovery. Choice B is incorrect as the main purpose of combining medications in HIV treatment is to prevent resistance rather than improving the immune system. Choice D is incorrect because while it is true that the medications may target different parts of the virus, the main reason for using both together is to prevent resistance.
